Definitions

• the present invention relates to a vehicle interior trim loudspeaker mounting subassembly, the subassembly comprising a cap wall that delimits a speaker housing, and a grille covering the housing comprising elastic fastening means cooperating with the wall of the cap.
• a motor vehicle is equipped with a dashboard with an upper cap visible from its occupants.
• small diameter speakers for example 30 mm diameter, commonly called tweeters can restore the high frequencies, the "treble" of the vehicle audio system.
• the location of choice of these small speakers is located in the cap near the windshield, near the side uprights so that the "treble” can spread almost ideally in the upper part of the passenger compartment. reflecting on the windshield.
• this region of the cap may be subject to deformation, for example during a violent shock, because of the shock itself but also because of the triggering of the pyrotechnic means actuating the airbags.
• This is not without problems in keeping the grille covering the speaker that can be detached from the cap and be projected into the cabin, possibly to the detriment of the safety of the occupants.
• the invention aims to improve such a subset.
• the subject of the invention is a subassembly for fixing the speaker grille of the interior trim of vehicle of the aforementioned type, the main means of elastic fasteners cooperate with a first portion of the housing and which comprises secondary retention means which, in a lower portion of the housing, separate from the first portion, comprise at least one female member of fastening in which engages at least one male fastening member.
• the fastener subassembly comprises one or more of the following features: the main elastic fastening means are formed on a ring at the periphery of a grille of the grid;
• the main means of resilient fixing are snap-fastening members hooked on the first part of the housing, which allows a catch in a flexible part of the dashboard which limits the noises and squeaks;
• the male fastening members of the secondary retaining means comprise a rod at the end of which is formed a foldable elastic portion during insertion of the male member into the female fastening member constituted by an orifice;
• the male and female attachment members of the secondary retaining means are in even number and arranged symmetrically about an axis of symmetry of the grid formed by a diameter of the grid, which can allow a single grid of power be indifferently adapted to both side ends of the dashboard;
• a structural element of the cap is the bottom wall of the housing, in that in a normal position of use, the end hooks of the male fastening members are at a distance from the orifice, under this last, and in a working position of the male hooking organs, in which the main resilient fixing means are unhooked from the cap wall, the end hooks cooperate with the housing bottom wall at the periphery of the orifice, which makes it possible to limit the noises and squeaks coming from the cooperation of these secondary means of restraint with a hard part of the dashboard;
• the elastic fixing means cooperate with at least one shoulder formed on the circumference of an upper part of the housing which is the first part, which makes it possible to have an increased fastening power on the cap.
• the invention also relates to a motor vehicle comprising a subassembly according to the invention, the subassembly being a subset ensuring the holding of the gate on the cap even during the deformation of the first part of the latter during an impact with deployment of the airbag.

• FIG. 3 is a view from above of the loudspeaker grille according to the invention
• FIG. 4 is a section of the loudspeaker grille in the subassembly according to the invention at the plane A-A of the figure.
• the first three figures, 1, 2 and 3 show the grid
• Figure 4 presents in section, the grid 10 in place on the dashboard cap 20 by covering a loudspeaker 30.
• the loudspeaker 30 comprises a casing 31 which generally supports a membrane 32, an electromagnet 33 and a connector 34.
• This casing 31 is itself mounted in a counterbore 23 in the lower part of a housing 21 of the cap 20, between an outer skin of the cap 20 and a structural wall.
• the housing comprises fastening means on the dashboard cap 20, not shown.
• the loudspeaker 30 must be able to be installed in the upper part of the cap 20, thus the upper part of the housing 21.
• the housing 21 is substantially cylindrical, and has a diameter greater than the diameter of the speaker 30.
• the grid 1 0 comprises main means for fixing the grid 1 0 on the cap 20.
• the wall 25 at the periphery of the housing 21 has a particular profile in the direction of the depth of the cap 20, for in its upper part, cooperate with the main means of fixing the grid 1 0.
• These means comprise elastic tabs 1 1 on a peripheral ring 1 2a of a grid 1 2 of the grid 1 0.
• Each leg 1 1 comprises a arm 1 1 a, connected at one end to the ring, at the end of which is located an end portion 1 1 b adapted to come into contact with the wall 25. This end portion 1 1 b is pressed against the wall 25 under the effect of the elastic return of the tabs 1 1 which are deformed towards the axis of revolution R of the mesh 1 2 when they are in place in the housing 21.
• a shoulder 22 is formed at least on a portion of the periphery of the housing 21.
• the end portion of the lugs 1 1b then has a surface capable of engaging under this shoulder 22 to strengthen the attachment and oppose the extraction of the grid 10 of the housing 21. This induces that the lugs 11 must be able to deform so as to pass inside the smaller diameter, formed by the shoulder 22 on the upper periphery of the housing 21.
• the housing 21 may become deformed, in particular during hot weather when the dashboard has remained several hours in the sun and its material , at the surface, at 70 ° C is less rigid than at 20 ° C.
• the main means of fixing may in certain cases be insufficient to prevent the ejection of the grid 10 out of the housing 21.
• secondary retaining means are provided to ensure that the grid 10 can not leave the housing 21.
• These secondary retention means cooperate with a lower portion of the peripheral wall 25 on a structure wall of the dashboard, in addition to the main means of attachment described above.
• the countersink 23 on which rests the speaker housing 31.
• the housing bottom wall 21, near the countersink 23, is formed at least one through hole 24 in which slide the secondary means of retention.
• These secondary retaining means are formed by the cooperation of the through-orifice 24 with harpoons 13.
• the harpoons 13 constitute an example according to this embodiment of the male fastening members of the secondary retaining means and the orifice 24 an example female hooking organs.
• retaining means are in the form of a rod 13a connected to the ring 12a at one end.
• the rod 13a is adapted to engage in the orifice 24.
• the harpoons 13 are in the form of elastic hooks 13b having at rest in the absence of any compression, larger dimensions than the orifice 24.
• hooks 13b must then be able to deform by folding along the rod 13a during the engagement of the harpoons 13 in the orifice 24 in an elastic manner so as to return to their original rest position. If these hooks 13b must be deformable to move along the rod 13a, these same hooks 13b must also be strong enough to hold the grid 10 to prevent ejection. During the elastic deformation of the hooks 13b which occurs at the time of ejection, their dimensions must remain greater than the dimensions of the orifice 24, without breaking. This requires to find a compromise between the elasticity sought for the engagement of these means 13 in the orifice 24 and the stiffness that these means 13 must present to oppose the ejection of the grids 10 out of the cap 20.
• the grid 10 has two harpoons 13 which are symmetrical with respect to each other with respect to a diameter of the mesh 12. If the presence of two harpoons 13 can make it possible to increase the safety, it can also make it possible to use the same grid 10 at each lateral end of the cap 20 in the vehicle, while retaining a means for producing the single housing 21 for the two lateral edges of the cap 24.
• the fastening means 1 1 and the retaining means 13 of the grid 1 0 on the cap 20 and the fixing means of the loudspeaker housing 30 on the cap 20 are separate and independent. This is particularly advantageous because in the same range of vehicles, some models have a tweeter and other models do not include tweeters. This system can then be unique for several versions of the same vehicle.
• a securing device for a protective grid according to the invention is therefore particularly advantageous by resorting to secondary retention means co-operating with a hard part of the dashboard when the main fixing means which cooperate with a flexible part of the board of edge, cooperation that has the advantage of not inducing noise or squeaks, have not proved effective enough to retain the protective grid.
